ICD-10 Code A24.2 – Subacute and chronic melioidosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A24.2 – Subacute and chronic melioidosis
What it is
A24.2 identifies subacute or chronic melioidosis, a prolonged infection caused by Burkholderia pseudomallei. Use it when documentation clearly states the infection is subacute or chronic rather than acute.
Clinical signs
Clinical features vary; refer to documentation. Chronic melioidosis may present with persistent fever, localized abscesses, pneumonia, or recurrent infection over time.
When to use this code
Use A24.2 when the provider documents subacute or chronic melioidosis, including prolonged or relapsing disease. This code fits confirmed melioidosis with a chronic course, whether the infection is pulmonary, disseminated, or localized, if the record supports that description.
Do not use for
Do not use this code for acute melioidosis, which is coded elsewhere. Check documentation if the record only says “melioidosis” without specifying the stage.
Coding tip
Assign A24.2 only when the chronic or subacute nature is explicitly documented; otherwise, query the provider.
